Based on EPA violation records. Check your ZIP code report for system-specific contaminant data.
Warren Infrastructure Age
With 88% of homes built before 1986, lead solder in plumbing is a potential concern. The EPA banned lead solder in 1986, but many older homes retain original plumbing.
Source: U.S. Census Bureau American Community Survey (ACS).
Housing Age Profile
When more than half a city's housing predates the 1986 federal ban on lead solder, plumbing-era lead risk becomes a citywide concern rather than an exception. Warren's median build year of 1965 places it squarely in that category.
Over half of homes in Warren were built before 1986, when lead solder was banned. Older plumbing may leach lead into drinking water, especially with corrosive water chemistry.

How Remediation Costs Compare in Warren
In Warren, the equity impact of remediation is proportionally small - not the kind of financial commitment that rises to the level of a genuine planning constraint, but a minor share of what most properties here are worth.
Remediation costs in Warren are relatively low compared to home values. The $1,080–$2,380 estimated range is a small fraction of median property value. Home values are 3% below the Michigan average.
Warren: Lead Risk & Vulnerable Populations
Why children are most at risk: The CDC states there is no safe level of lead exposure for children. Children under 6 absorb lead more readily than adults, and even low levels can cause developmental delays, learning difficulties, and behavioral problems.
Older stock in Warren represents 88% of the inventory, and citywide monitoring runs at or above the federal action level - making an in-home read a standard household-level step.

Warren: NFIP Claim Records and Water-Quality Context
Historical NFIP data for Warren contains 38 flood insurance claims. Among claims with payment data, the average reported building, contents, and ICC component sum is $33,879. Among ZIP codes with claim records, 20% have an A- or V-family dominant rated zone recorded in those historical claims. This is not a complete current FEMA property-map inventory.
How flooding affects water quality: Flood events can introduce sewage, agricultural runoff, and industrial chemicals into water supplies. Even after floodwaters recede, contamination can persist in wells and aging infrastructure. The <strong>$1,580</strong> remediation estimate shown here excludes flood insurance and is not derived from NFIP claim count.
Claim count does not establish current property risk. Check the exact address in FEMA's current map and obtain a property-specific insurance quote when relevant.
